Multi-display Image Position Coordination for Deterioration Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-displays using light emitting display apparatuses, individual adjustment of image position leads to image loss when each apparatus changes its display position, as there is no sharing of information between the apparatuses to compensate for deterioration and maintain image coherence.
Innovation Solution
A multi-display system where at least two light emitting display apparatuses share information for varying image positions through a distributing device and controllers, allowing coordinated adjustment of image data distribution to minimize image loss across the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each light emitting display apparatus individually varies the position at which an image is displayed to compensate for deterioration, then the deterioration compensation is achieved, but image loss occurs due to lack of coordination between apparatuses
Solution Approach 1:
The patent merges the control functions of multiple light emitting display apparatuses into a unified system. The image position variation for deterioration compensation is coordinated across all apparatuses through a master controller that manages the multi-display system, ensuring that when one apparatus shifts its image position, adjacent apparatuses compensate accordingly to maintain continuous image coverage without loss.
Solution Approach 2:
The system implements feedback mechanisms where each light emitting display apparatus monitors its own image position and deterioration status, and communicates this information to the master controller. The master controller then adjusts the image position commands for each apparatus based on real-time feedback, ensuring coordinated movement that prevents image loss while achieving deterioration compensation.
2Ease of operation
If image position is varied in each light emitting display apparatus independently, then device autonomy is maintained, but image coherence is lost across the multi-display system
Solution Approach 1:
The patent segments the control system into a master controller that manages overall image coherence and individual apparatus controllers that handle local operations. This segmentation allows each apparatus to maintain operational autonomy for routine functions while the master controller coordinates image position variations across the entire multi-display system to preserve image coherence.
Solution Approach 2:
The master controller acts as an intermediary between the individual light emitting display apparatuses. It receives autonomous operation requests from each apparatus, coordinates image position variations to maintain coherence, and distributes adjusted commands back to each apparatus, thereby mediating between device autonomy and system-wide image coherence.

AI summary
Disclosed is a multi-display in which light emitting display apparatuses share information for varying a position of an image. The multi-display includes: at least two light emitting display apparatuses; and a distributing device distributing pieces of multi-image data transmitted from an external system to the light emitting display apparatuses, wherein a first controller controlling a function of a first light emitting display apparatus among the light emitting display apparatuses shares information for varying a position of an image with controllers controlling functions of the other light emitting display apparatuses. According to the multi-display of the present disclosure, even if the multi-image is shifted in various directions in order to prevent deterioration of the light emitting display apparatuses in the multi-display, a lossy image may be minimized or reduced.
